Former couple Kieron Ducie and Ann Corcoran will be sentenced next year at Trim Circuit Court after admitting the drugs charge, which dated to December 2007.

Ms French, 24, died in hospital on December 6, four days after she slipped into a coma at their home in Kilmessan, Co Meath.

A post-mortem examination revealed she suffered brain damage and traces of cocaine were found in her system.

The pair admitted that between 6pm on Saturday December ,1 2007, and 10am the following day they, at an unknown location, procured Russell Memery to possess cocaine for the purpose of sale or supply.

Judge Leonie Reynolds was told a second charge would not be pursued against Ducie and Corcoran - that they intentionally or recklessly engaged in conduct related to the supply of cocaine to Ms French and failed to get medical assistance in a timely fashion, which created a substantial risk of death or serious harm to another.

Ducie, 43, of Lambertstown Manor, Kilmessan, Co Meath, and Corcoran, 31, of Tolka Road, Clonliffe, north Dublin, both spoke only to say "guilty" during the short hearing.

Born in Switzerland, Ms French and her family moved to Ireland when she was a young girl and settled in Enniskerry, Co Wicklow.

She had celebrated her 24th birthday days before she collapsed at the former couple's house in Kilmessan.

Her parents John and Janet and sister Jill maintained a bedside vigil for four days as the model lay critically ill on a life support machine at Our Lady's Hospital in Navan.

Her mother and sister were supported in court today by gardai, and left the courthouse without speaking about the case.

They are expected to return when Ducie, who was dressed in a dark suit and yellow tie, and Corcoran, who wore a long dark coat, are sentenced on February 5 next year.

Ms French, a model and socialite, became a tabloid darling in the two years before her death.

She previously revealed she had used cocaine, branding it part of the Dublin social scene, but claimed she had quit the drug, warning others of its dangers.

Olympic champion swimmer Michelle de Bruin, rugby star Shane Byrne and singer Chris de Burgh, along with friends and colleagues from the modelling and fashion world, were among the hundreds of mourners who packed St Patrick's Church, Enniskerry, for her funeral.
